Solve for x given the equation vx+9 -4=1. extraneous or not

For this case we must find the value of "x" of the following equation:

We add 4 to both sides of the equation:

We raise both sides of the equation to the square to eliminate the radical:

We subtract 9 from both sides of the equation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
